What’s the secret to a long and healthy life? All centenarians have their own habits and morning routines they swear by. From whiskey shots to daily naps to ice cream, here's what some very old people credit for their lengthy lifespan.

In 2011, Huffington Post interviewed a centenarian named Ruth. Since the age of 92, Ruth has committed to weekly Pilates classes. She also has a mean sense of style.

1. “Don’t look at the calendar. Just keep celebrating every day.”

2. “Invest in quality pieces, they never go out of style.”

3. “I make myself go out every day, even if it’s only to walk around the block. The key to staying young is to keep moving.”

44. “We all remember how as children, when we were having fun, we often forgot to eat or sleep. I believe that we can keep that attitude as adults, too. It’s best not to tire the body with too many rules such as lunchtime and bedtime.”

45. “For breakfast I drink coffee, a glass of milk, and some orange juice with a tablespoon of olive oil in it. Olive oil is great for the arteries and keeps my skin healthy. Lunch is milk and a few cookies, or nothing when I am too busy to eat. I never get hungry because I focus on my work. Dinner is veggies, a bit of fish and rice, and, twice a week, 100 grams of lean meat.”

46. “There is no need to ever retire, but if one must, it should be a lot later than 65.”

47. “When a doctor recommends you take a test or have some surgery, ask whether the doctor would suggest that his or her spouse or children go through such a procedure. Contrary to popular belief, doctors can’t cure everyone. So why cause unnecessary pain with surgery? I think music and animal therapy can help more than most doctors imagine.”

48. “To stay healthy always, take the stairs and carry your own stuff. I take two stairs at a time, to get my muscles moving.”

49. “My inspiration is Robert Browning’s poem 'Abt Vogler.' My father used to read it to me. It encourages us to make big art, not small scribbles. It says to try to draw a circle so huge that there is no way we can finish it while we are alive. All we see is an arch; the rest is beyond our vision but it is there in the distance.”

50. “Pain is mysterious, and having fun is the best way to forget it.”

51. “Don’t be crazy about amassing material things. Remember: you don’t know when your number is up, and you can’t take it with you to the next place.”

52. “Science alone can’t help or cure people.”

53. “Find a role model and aim to achieve even more than they could ever do.”

54. “It’s wonderful to live long. Until one is 60 years old, it is easy to work for one’s family and to achieve one’s goals. But in our later years, we should strive to contribute to society. Since the age of 65, I have worked as a volunteer. I still put in 18 hours seven days a week and love every minute of it.”

66. “[Humor is] a life force, a way of surviving the difficulties of living.”

67. “When you laugh at yourself, you prevent others from laughing at you.”

68. “I think [people] have to be curious. They have to be interested in life outside their little aches and pains. They have to be excited about seeing new things, meeting new people, watching a new play—just passionate about life.”

On Reddit, a grandson created a thread where he allowed people to ask his 101-year-old grandmother for advice. This is what happened:

72. “Be honest. I’ve rarely lied. And when you are honest with people, it comes back to you, and they are honest with you. It’s too much work keeping up with a lie. You don’t need the extra stress.”

73. “Keep an open mind, and things seem less strange.”

74. “Always listen to the other person. You’ll learn something. Try to sit back, because you will learn a lot more listening to others than telling them what you know.”

75. “You have to love what you do. if you find a job you love, you will never have to work a day in your life.”

76. “Take naps every day.”

77. “You get one family, so stick with them. But it depends if these hardships are financial or emotional or other types. Stick it out. Some days are worse than others, and you have to be ok with that. The night is darkest before dawn.”

78. “I try to take the time to look at and appreciate the smaller things that make this life beautiful. When I do that, time slows.”

82. “I participate in lots of activities. I play Bingo, do meditation and crafts, and attend fitness classes, like Zumba Gold for seniors, chair yoga, and sittercise… I don’t miss happy hour either! I drop in three times a week.”

83. “Be lovable. I’ve lived a long life because there are so many people who love me.”

89. “Laughter keeps you healthy. You can survive by seeing the humor in everything. Thumb your nose at sadness; turn the tables on tragedy. You can’t laugh and be angry, you can’t laugh and feel sad, you can’t laugh and feel envious.”

90. “Look inside your soul and find your tools. We all have tools and have to live with the help of them. I have two tools: my words and my images. I used my typewriter, computer, and my cameras to fight injustice. Whenever I see a possibility of helping people who are in danger, I want to help them.”

91. “Have a good appetite, lots of friends, and keep busy.”

92. “Have a good wife, two scotches a night, and be easygoing.”

93. “Never run out of responsibility; if you don’t have one, find one. Find a cause and knock yourself out for it. It will enhance your brainpower, interest in life, and keep you alive longer. I’m alert because I work. Virtue is its own reward.”
